Bob is an Examiner for Alpine skiing in the Rocky Mountain division of PSIA and a member of the Alpine Committee. He is a supervisor in the Copper Mountain Ski School and an outstanding skier and technician. I find this book to have all the practical information needed for Instructors and skiers alike. On top of that, expect some humor to be mixed in along the way. This is a book that all skiers should own. I'm sure you will enjoy it.
